Title: Inspection of resist pattern
Inventor: SAKA TAKETORA
IPC: H01L21/027
Filed: 1987-03-20
Abstract: PURPOSE:To determine the execution of exposure according to a pattern before development treatment by exposing and treating a photosensitive resin film, irradiating the film with an He-Ne laser and detecting the Raman scattering of the reflected beams of the laser. CONSTITUTION:A resist film formed onto a substrate and selectively irradiated with energy beams is irradiated with monochromatic beams having a wavelength where a high molecular material for the resist film is not photosensitized, and Raman scattered beams in reflected beams from the substrate are observed. When a resist 9 is irradiated with energy beams such as ultraviolet rays, electron beams, etc., it generates a chemical change, and the natural frequency of C-H bonds, C=0 bonds, etc., alters, thus shifting the wavelength of Raman scattered beams. Since a Raman effect is also generated in reflected beams from the resist 9, reflected beams from He-Ne laser beams 1 are spectrally diffracted by a monochromator 4, and projected to a detector having high sensibility such as a photomultiplier 5 and Raman scattered beams having a specific wavelength are detected, thus determining the generation of the chemical change with photosensitization in the resist.

Title: Glass fiber bundle photodetector
Inventor: NAKAMURA KOUJI
IPC: G02B6/04
Filed: 1980-05-19
Abstract: PURPOSE:To improve the measuring accuracy of a glass fiber bundle photodetector by disposing a light diffusing plate at the emitting end of a condensing glass fiber bundle and detecting it by a photodetector disposed at an interval, thereby reducing the variation in the detection signal. CONSTITUTION:A light diffusing plate 2 of opal glass or the like is disposed at the end terminal 6 of a condensing glass fiber bundle 1 for condensing incident light 5. The diffused light 7 from the plate 2 is detected by a photodetector 3 disposed at a predetermined interval l. When the l is set at 6.2 times of the radius H of the emitting end of the glass fiber bundle, the range of variation in the quantity of light received by the photodetector is reduced to 5%. When the light diffusing plate 2' disposed at the emitting end is bent to match the spherical surface having a diameter of the distance to the photodetecting surface of the photodetector 3, any incident light becomes constant luminous flux. Thus, it can reduce the variation in the detection signal and can improve the measuring accuracy.

Title: Input device
Inventor: SAKAKIBARA ATSUSHI
IPC: G06F3/023
Filed: 1985-04-01
Abstract: PURPOSE:To avoid the misinput of keys by invalidating the input of a key for size of a character in case the operating combination is prescribed between one of shift keys for types of characters and shift keys for sizes of characters. CONSTITUTION:A mode flag MF set on a RAM is set at '0' for decision of the presence/absence of input of a key. If the key input is confirmed, it is decided whether or not the input key is equal to one of shift keys K1-K4 for types of characters. If it is decided the input key is equal to one of a HIRAGANA (Japanese syllabary) shift key K2, a KATAKANA (square form of Japanese syllabary) shift key K3, a mark shift key K4 and an alphabetic shift key K1, the value of the mode flag corresponding to the flag MF is set. Then it is decided whether the flag MF has the prescribed value or not as long as the input of the key K5 is confirmed. IF the flag MF is not set at the prescribed value, the value corresponding to the K5 is added to the value of the flag MF. Then the input of the K5 is invalidated if the flag MF has the fixed value based on the result of said addition. In other words, the key input is invalidated if it is not proper.
